Gray

Appearance: Gray has white hair (someone in the fandom even jokingly compares it to aloe vera leaves) with his bangs hanging down and the rest of his hair combed upward. His eyes are purple. He usually wears a black headband, a jacket, a blue t-shirt, dark blue pants, a belt with yellow details, and dark blue shoes. He also wears white gloves with black stars; the glove on his left hand is black, the glove on his right is white. His weapon is a green blade with two black stripes, a white hilt, and a hollow pentagonal pommel.
Gray is one of the main characters in "The World of Aotu," the last survivor of the Observer Clan. His planet was destroyed, and Gray himself was sent into space in an escape capsule as a child. He spent about 100 years in cryosleep before awakening and training to uncover the mystery of his clan's demise.
Personality: Gray often has a calm, almost emotionless expression; he keeps everything to himself and is used to dealing with difficulties alone. At the same time, he is very loyal to those close to him: he is especially close to King (they have known each other since childhood), and he cares deeply for him, but doesn't like to show it openly. Gray is always on guard and ready to act, especially when it comes to something dangerous.
Abilities: His signature skill is "Hyper Cutter." Gray can strike not only with his blade but also with energy waves, and can also create square barriers for defense or to block the enemy's path. In its advanced mode, the skill transforms into a massive sickle-shaped blade.

What is this event? The tournament brings together fighters from different planets to determine the strongest. It includes qualifying rounds, team and individual matches, and challenges that test not only combat skills but also the ability to make quick decisions.
The tournament is closely linked to a system of meta-skills—special abilities that fighters develop and utilize in battle. The arena and rules are designed in such a way that not only strength and speed come to the fore, but also strategy, and sometimes even unexpected alliances between participants.
The Aotu Tournament is an interplanetary competition that forms the core of the plot of "World of Aotu." It's not simply a competition for victory: many participants have personal motives, such as searching for truth, family, or power.
